Age of Heroes
The Age of Heroes was an era during the history of Westeros from which the beginnings of many noble houses trace their family histories.

It was during this age that Lann the Clever, Bran the Builder and other famous personalities were reported to have existed. It is an era that is shrouded in mystery, with more myth than fact known about it. It ended with the onset of the Long Night.
